Did you wash it down with sugar soap or anything else first. have you panted any other surfaces and not had coverage problems?
Smoke or nicotine on surfaces can bleed through if not well washed off first.

Hit it with a stain blocker. Loads out there my favourite is Zinsser bullseye 123 or zinsser BIN, but have a look in your local DIY store plenty to choose from. Do two coats then hit it with your topcoat.
If it is nicotine it may bleed through the first coat but will be locked in and the second will block it.(y)

123 is water based easy clean up, BIN is solvent based, brushes need cleaning in methylated spirit, slightly harder to apply but better for things like resin and knots.

Seriously, buy some household ammonia for cleaning the brushes after. Meths only dilutes the shellac, ammonia is alkaline and breaks it down completely. I have used it to clean Purdys that I had bagged up after working with BIN, with the intention of cleaning them shortly after, then forgotten all about them. A week later I can still drop them in to the ammonia and leave them for a while and they are as good as new after (just wash them with water). The only downside is that the ammonia stinks- I leave the open kettle undercover outside whilst it works overnight. In the morning, the ammonia has evaporated and I am left with a container that has water and "white dust" in the bottom. It is safe to pour down the sink and unlike the meths it leaves no residue/mess. It is also cheaper than meths.

I cannot stress how much better ammonia is than meths for cleaning up brushes.
